WAVELENGTH 8-12um 13.5mm FOCAL LENGTH F#1.2 12UM Athermal Lenses FOR INFRARED CAMERA
WAVELENGTH 8-12um 13.5mm FOCAL LENGTH F#1.2 12UM Athermal Lenses FOR INFRARED CAMERA
The need to maintain focus over a wide range of environmental temperatures is essential to system performance, stability, and high quality. Athermalized lenses kept their performance from changing by means of optical passivity, mechanical activity, and mechanical passivity in a large temperature range. Its configuration will auto-adjust itself when placed at different temperatures.
The 8-12µm LWIR Athermal Lens (13.5mm F#1.2) is designed for thermal imaging cameras. It maintains stable focus from -40°C to +80°C without active adjustment. With >90% transmission and a lightweight 9.1g design, it is ideal for surveillance, drones, and industrial inspection. HDAR/AR coatings available.
